FIREPROOF WINDOW.

SPECIFICATION forming part of Letters Patent N 0. 651,096, dated June 5, 1900.

I Application filed January 29, 1900- Serial No; 3,149. (No model.)

To all whom it may concern:

Be it known that We, DANIEL B. BADGER, of Winchester, in the county of Middlesex, and ARTHUR O. BADGER, of Boston, in the county of Sufiolk, State of Massachusetts, have invented certain new and useful Improvements in Fireproof lVindows, of which the following is a specification.

This invention relates to fireproof windows in which the sash and'frame are made of sheet metal bent to the desired form and secured together in properplaces. The invention has for its object to improve the general structure of windows of this character, so as to provide a simple and at the same time strong and highly resistant structure.

The invention also has for its object to provide improved means for readily obtaining access to the sash-weights and'removing sashes from the frame.

To these ends the invention consists in certain novel features of construction and arrangement, which we will now proceed to describe and claim.

Of the accompanying drawings, Figure 1 represents a front elevation of a Window constructed in accordance with our invention. Fig. 2 represents an enlarged front elevation, partly broken away and in section, showing one side of the frame and sashes. Fig. 3 represents a section on the line 3 3 of Fig. 2. Fig. at represents a section on the line 4 4 of Fig. 2. Fig. 5 represents a detail perspective view of the lower end of the removable panel or stile section of the window-frame. Fig. 6 represents a cross-section of the upper corner of the sash. Figs. 7 and 8 represent detail sectional views illustrating the manner of formation of the inner corner of the joint between the vertical and horizontal rails of the Window-frame; Fig. 9 represents a detail sectional view of the outer corner-joint of the frame-rails. Fig. 10 represents a horizontal section of the side sash-rail. Fig. 11 represents a section on the line 11 11 of Fig. 1 looking in the direction of the arrow.

The same reference characters indicate the same parts in all of the figures.

Referring to the drawings, 1 designates generically the window-frame, and 2 and 3 designate the lower and upper sashes, respectively. Both frame and sashes are made of sheet metal bent into form, and the panes of the sash are preferably composed of wire glass.

Referring to the detail construction of the sashes, it is to be noted that the side rails 4 thereof are composed of a body-strip 5, bent to form the front and rear facesand the inner edge of the rail, said inner edge being recessed or grooved at 6 to receive the pane 7, and an outer strip 8, connected at its edges to the two edges of the said body-strip 5. An interlocked jointis formed between the body and outer strips, as shown clearly in Fig. 10, said joint being constructed by doubling each edge of the body-strip 5 back on itself and then outwardly to form a groove, which receives an inwardly-turned lip 9, formed on the outer strip 8. The joint is made on the inside, so that outwardly the sash-rail presents a smoothappearance. To reduce friction of the sash-rail against the sash-guides or stiles of the frame, the outer strips 8 of the side rails are bent or convexed inwardly, as illustrated.

The center or cross rail 10 of each sash, as shown in Fig. 4, is made up of two strips 11 11, bent so as to form grooves on opposite sides of the rail, to receive the edges of the panes 7 7, one end of each strip 11 starting at 12 on one side of the bottom of the panereceiving groove and after forming one-halfof the external body of the rail passing across the interior space of the rail in the form of a lip or web, which preferably meets the outer wall of the rail and serves to stiffen and strengthen the said rail. The ends of the grooved rails 10 are connected to the top and bottom rails of the sashes by the construction represented in Fig. 11, in which 14 represents the bottom rail of the sash, and 15 15 represent prongs formed on the end of the cross-rail and projecting through holes in the upper wall of the bottonrrail, said prongs being bent over parallel to and again'st the said wall, so as to securely attach the rails together. 1

The top rails 16 of the sashes are formed of two side body-strips, whose lower edges 17 17 are turned up into the center of the rail and separated by a narrow space slightly wider than the thickness of the pane 7, which forms a slot 18 for the introduction and removal of the said pane. The upper edges of the body-strips are separated by a wider space and are turned downwardly to form lips or guides 19 for guiding a slide or cover 20, which forms the upper face of the rail and is displaced when it is desired to remove or IO insert the pane 7.- The slide is composed of a single strip having its edges bent back toward each other underneath the top of the slide and turned downwardly and upwardly around the edges of the lips or guides 19 .19, [5 so as to form grooves for receiving said guides. The slide 20 is moved into and out of place by a horizontal movement longitudinally of the top rail 16 and is provided with a downwardlyturned lip 21 on one end, which abuts against the vertical edge of the sash when the slide is moved into place, as shown in Fig. 6, the said figure representing a section taken in a vertical plane diagonally across the upper corner of the sash. The side edges of the slide 20 are brought substantially flush with the vertical front and rear faces of the sashrail, so as to give the sash a smooth exterior unobstructed by any projecting flanges.

Slides 50 and 51, similar to the slides 20 on the top rails of the sashes, may be provided on the lower sides of the bottom rails of said sashes, so as to give access to the interior of said bottom rails; but these bottom slides may be dispensed with, if desired.

Proceeding next to the construction of the window-frame 1 it will be noted in Fig. 2 that the joint between the side rail 22 and top rail 23 of the frame is made by lapping over the ends 24 25 of the side strips of said rails and securing them together by rivets 26 26, while the inner walls 27 28 of said rails are connected together securely by a joint 29. The joint 29 is shown in detail in Figs. 7 and 8. In forming it the wall or strip 28 is first bent out horizontally and the strip 27 bent around under it, as shown in Fig. 7, and then the interlocked seam thus formed is doubled over against the base of the strip 28 and fastened through with rivets 30.

. The top and bottom rails 23 31 of the window-frame are of a formation similar to each other and comprise body-strips 32 34, bent to form the front and rear faces and the inner face of said rails and outer strips 33 35, whose edges are connected to the edges of the body-strips by inwardly-turned interlocked joints. The inner faces of the rails are suitably formed to receive the upper and lower sashes. The side rails 22 are formed with the body and outer strips 36 37 and with a cross strip or web 38, dividing the side rail into two weight-boxes, the edges of the web being held in grooves formed by flanging the outer and inner faces of the rail at 39 and 40. The flange 40 divides theinner face or stile of the framerail into two vertical guides for the upper and lower sashes, the opposite sides of said guides being formed by bending the shoulders 41 41 in the body of the rail.

42 is a movable panel or plate forming the lower section of the sash-guide or stile and having a height somewhat greater than the height of the lower sash. Said panel is equal in width to both sash-guides and is held in place by having its upper end 43 located behind the lower edge 44 of the fixed upper section of the stile, while its lower end is secured to the frame by means of buttons or catches 45 engaging a fixed upturned lip 46 on the frame and having stems with slotted heads 47, exposed on the inner sides of the panel 42 and adapted to receive a screw-driver or similar instrument, by means of which the catches are turned to release them from the lip 40. The panel may thereupon be removedfrom place, so as to expose the weights contained in the weight-boxes and also permit the sashes to be displaced laterally, so as to remove them from the frame. The panel 42 has outwardlyturned vertical flanges or lips 48, which fit into grooves 49 49, formed on the edges of the body-strips 36 and serving to limit the outward movement of the panel. The lower portion of the web 38 on one side of the frame may be made separate from the upper portion and attached to the removable panel 42, so

as to be removed when said panel is taken out, thereby giving increased room for manipulating the sashes when the latter are taken out of the frame. The inner edge of the removable section of web or partition 38 will preferably be fixed in the fold or flange 40 in the panel and its rear edge adapted to enter the fold or flange 39 when the panel is in place.

We claim- 1. In a fireproof window, a sheet metal frame having a plate or panel constituting the lower part of the stile or sash-guide and detachable from the body of the frame so as to expose the weights, the upper end of said panel fitting behind the fixed upper section of the stile or guide, the frame having a fixed upturned lip back of the lower end of the panel, movable catches on the panel securing the lower end of the panel to the said upturned lip and adjustable from the inner or exposed face of the panel, and means to limit the outward movement of the panel.

2. In a fireproof Window, a sash having a hollow sheet-metal top rail slotted vertically for the introduction of the pane, the body of said rail terminating on top in separated downwardly-bent lips forming guides, and a slide forming the top of said rail and substantially flush with the vertical front and rear faces of the rail-body, said slide being movable lengthwise of the body of the rail, into and out of engagement therewith and having guides e11- gaging the guides on the rail-body and consisting of lips bent around the said lips or guides on the rail-body.

3. In a fireproof window a sheet metal frame having the joints between its vertical IIO and horizontal rails lapped and riveted on the faces and the inner sides thereofinterlocked and doubled over and riveted, as set forth.

4. In a fireproof window, a sheet-metal sash having a cross-rail composed of two strips bent to form grooves on the opposite sides of the rail to receive the pane, one edge of each strip being continued across the interior of the rail to form an inner strengthening-web.

5. In a fireproof window, a sash having a hollow sheet-metal rail, and a hollow sheetmetal cross-rail connected to it, the connection being by means of a series of integral prongs formed on the end of the cross-rail and passing through holes in the nearest wall of the first said rail and bent over within the interior of said rail parallel to said Wall.

6. In a fireproof window, a frame having a removable panel forming the lower part of the stiles or guides for both sashes and detachable from the upper part, and a web attached to said removable panel and constituting the lower part of the partition between the weight-boxes.

In testimony whereof we have affixed our signatures in presence of two witnesses.
